Hey all,
This book is for my Eternity Realms game, which is licensed from Mongoose's Legend so is highly compatible, almost flawlessly in fact except where the NPC's are concerned, but that can easily be modified.

Within this tome is a wide assortment of monsters for use in any d100 game. Converting many monsters from the d20 system, the Gigas Monstrum uses many of those epic creatures and turns them into grueling combatants, specifically for use in the Eternity Realms setting. Take your brave adventurers and take on the horrors within. Adventure awaits

Thanks, auyl! That's very handy as I am about to start a Legend / Classic Fantasy campaign based on large pile Pathfinder/d20 books. They use a lot of critters from those tomes, so I am going to order the lot. Will make my GMing a lot easier.
